This study employed contingent valuation method to estimate the willingness to pay (WTP) of the households to improve the waste collection system in Kuala Lumpur, Malaysia. The objective of this study is to evaluate how household WTP changes when recycling and waste separation at source is made mandatory. The methodology consisted of asking people directly about their WTP for an additional waste collection service charge to cover the costs of a new waste management project. The new waste management project consisted of two versions: version A (recycling and waste separation is mandatory) and version B (recycling and waste separation is not mandatory). The households declined their WTP for version A when they were asked to separate the waste at source although all the facilities would be given to them for waste separation. The result of this study indicates that the households were not conscious about the benefits of recycling and waste separation. Concerted efforts should be taken to raise environmental consciousness of the households through education and more publicity regarding waste separation, reducing and recycling.
本研究采用意愿调查评估法来估算吉隆坡家庭愿意为改善垃圾收集系统支付的意愿（WTP）。本研究的目的是评估当源头的回收和废物分类成为强制性要求时，家庭 WTP 会如何变化。该方法包括直接询问人们对额外的垃圾收集服务收费的支付意愿，以支付新的废物管理项目的费用。新的废物管理项目有两个版本：版本 A（强制回收和废物分类）和版本 B（不强制回收和废物分类）。当被要求对垃圾进行源头分类时，家庭对版本 A 的支付意愿下降了，尽管所有的设施都会提供给他们进行废物分类。这项研究的结果表明，家庭对回收和废物分类的好处没有意识。应该通过教育和更多关于废物分类、减少和回收的宣传，来共同努力提高家庭的环境意识。
